ROOFING PLATE OR SHINGLE.

SPECIFICATION forming part of Letters Patent No. 487,372, dated December6, 1892.

Application filed February 24, I892- Serial No. 422,653. (No model.)

To otZZ whom it may concern:

Be it known that I, LEVI H. MONTROSS, a subject of the Queen of GreatBritain, residing at Camden, in the county of Camden and 5 State of NewJersey, have invented a new and useful Improvement in Roofing Plates orShingles, of which the following is a specification.

My invention consists in a roofing plate or shingle composed of a singlepiece of sheet metal or other suitable material which has one edge orside turned up for forming a vertical or upright locking-tongue. Theopposite side of the shingle is struck up or bent into a longitudinalrib of a curved or other required shape and transverse section, thedepending edge of which is bent inwardly and upwardly upon itself andreturn-bent to form a vertical or upright locking loop or groove forengaging with the locking-tongue of the adjacent plate or shingle of thesame row, and thus make a vertical or upright lock-joint, having agutter and nailing strip integral therewith.

On reference to the accompanying sheet of drawings, making part of thisspecification, Figure l is a top and perspective view of a roofing plateor shingle which embodies my invention; and Fig. 2 is afull-linetransverse section through the line 1 2, Fig. 1, showing thelocking-tongue, longitudinal rib, lockingloop, drip-gutter,nailing-strip, and the locking-tongue of an adjacent shingle in dottedines.

Similar letters refer to similar partsin both views.

A is a roofing plate or shingle composed of a single plate of sheetmetal or other suitable material B, which has one side or edge turned upto form a longitudinal and vertical or upright locking-tongue C and itsopposite side convexed or struck up to form a longitudinal rib D of acurved or any other required shape and transverse section. The dependingedge e of said rib D is doubled or bent inwardly and upwardly andreturn-bent to form alongitudinal and vertical or upright locking loopor groove E. The inner side or return-bend d of said looking-groove Ehas a drip-gutter e and a nailing-strip f integral therewith. Forornamentation and imparting strength and rigidity the top of the shinglehas struck up transverse ribs g h, and the bottom is illwardly bent andcrimped at 'i In putting my invention in practice the first plate orshingle is properly laid on the roofboarding or shingle substructure andsecured by nailing through its nailing-strip or edging f. The adjacentshingle is joined thereto by holding it at a convenient inclination and'60 slipping its locking-tongue G into the locking loop or groove E ofthe preceding shingle, after which it is pressed down and nailed. Itwill be seen that each following shingle of a row covers the precedinggutter e and overlaps the nailing-strip, whereby the nails are protectedfrom sun-drawing.

I claim- 1. A roofing plate or shingle composed of a single piece ofsheet metal or other suitable 7o material, which is longitudinallyribbed, said rib having its depending edge bent inwardly and upwardlyupon itself and return-bent to form a vertical or upright longitudinallocking loop or groove, having a gutter integral therewith, for thepurpose shown and described.

2. A roofing plate or shingle composed of a single piece of sheet metalor other suitable material, which is longitudinally ribbed, said ribhaving its depending edge bent inwardly and upwardly upon itself andreturn-bent to form a vertical or upright longitudinal locking loop orgroove, having a gutter and a nailing-strip integral therewith, for thepurpose shown and described.

3. A roofing plate or shingle composed of a single piece of sheet metalor othersuitable material, which has one edge turned up for forming avertical or upright locking-tongue and the other edge longitudinallyribbed, which rib is bent inwardly and upwardly upon itself to form avertical or upright longitudinal locking loop or groove, having a gutterand a nailing-strip integral therewith,f0r the purpose shown anddescribed.

In testimony whereof I affix my signature in presence of two witnesses.

LEVI H. MONTROSS.
